title: RETRACTED: The evaluation of computed tomography scans and ultrasounds in the differential diagnosis of periapical lesions.
abstract: Traditionally, the definitive diagnosis of periapical lesion depends on histopathological examination of the tissues, which is impractical in cases planned for nonsurgical treatment. Recently, some authors have used ultrasound with power Doppler and computed tomography in differential diagnosis between a cyst and a granuloma. The aim of this study was to evaluate and compare the use of computed tomography (CT) scan and ultrasound with power Doppler flowmetry in differential diagnosis of periapical lesions. Twelve periapical lesions were imaged with the help of CT scans and ultrasound with color-power Doppler flowmetry. A provisional preoperative diagnosis was made based on history, clinical presentation, and radiographic features. The cases were treated by surgical endodontics. In all 12 cases, the diagnosis with CT scan and ultrasound coincided with the histopathological diagnosis of the lesions. It is proposed that CT scans and ultrasound with power Doppler flowmetry can provide an additional dignostic tool without invasive surgery, where treatment option is nonsurgical.
